There appears to be a lot of confusion about indicators and how to use them for steering. Just a simple illustration of how processes work.

You put something in them (input), you do something with them (throughput) and you get a result (output). And so you have randomness, noise and external factors that may affect your result (ending in something we will call outcome). You can largely control output, outcome not so much. Make sure your performance isn't measured against outcome parameters, rather use one of the other three. That doesn't mean that you shouldn't monitor outcome parameters at all, but regard them as an indicator and initiation of further investigation, nothing more.
